Lava Land
Photograph by Carsten Peter

Hardened swirls of unusual natrocarbonatite lava pave the crater floor of Tanzania's Ol Doinyo Lengai volcano. The fresh black flows, less than 24 hours old, will rapidly harden and change to gray, then to powdery white. The mountain is the only active natrocarbonatite volcano on Earth, though scientists have spotted similar flows on the surface of Venus.
